The Work Does Not End When the Scaffolding Comes Down

Once a new pitched or flat roof is complete and the scaffolding is down, most homeowners understandably put the whole thing out of their mind. That is natural - it has been stressful, it has cost a lot, and you want it to just work. But a small amount of attention over the years that follow makes a real difference to how long the roof performs without problems.

This page covers what a new roof actually needs from you, what to look out for and what simple steps prevent the most common causes of early failure.

What a New Pitched Roof Involves

A new pitched roof strips the old covering to the timbers, replaces any compromised rafters or battens, installs a breathable underlay, fixes new battens at the correct gauge and then lays tiles or slates from the eaves up. Ridge tiles and hip tiles are pointed in mortar or fixed with a dry-fix system. Flashings at chimneys, dormers and abutments are cut and dressed in lead or lead-compatible materials.

For extensions and single-storey structures in Thetford, a flat roof replacement typically uses torch-on felt or an EPDM rubber membrane over a sound timber deck. Each of these systems has slightly different maintenance needs, but the principles are the same: keep debris clear, keep water moving and catch small problems before they become large ones.

Inspecting Your Roof After the First Winter

The first winter after a new roof is fitted is the most useful time for a follow-up look. Frost, wind and sustained rain test the new pointing, the flashings and the tile fixings in a way that no dry-weather installation can replicate. Looking at the roof from the ground with binoculars after the first hard winter costs nothing and can catch any settling issues early.

What to look for from the ground:

• Any tiles or slates that appear to have shifted, lifted at the edge or are sitting at a different angle to their neighbours
• Ridge or hip tiles where the mortar pointing looks cracked or has dropped away
• Flashings at chimneys or abutments that have pulled away from the wall, even slightly
• Any visible debris accumulating in valleys or gutters
• On a flat roof extension, any visible pooling after rain that has not drained within 24 hours

None of these observations require you to get onto the roof yourself - and you should not. A pair of binoculars and a critical eye from the garden or an upstairs window is enough.

Gutters and Downpipes - the Most Neglected Part of Roof Maintenance

Gutters and downpipes are not glamorous, but blocked or damaged guttering causes more secondary roof damage than almost anything else. When a gutter overflows consistently, water runs down the fascia, soaks the rafter ends and begins rotting the timbers that support the roof edge. By the time that rot is visible from inside, it has usually been developing for two or three years.

Cleaning gutters once a year - or twice if there are trees nearby - is one of the cheapest forms of roof maintenance available. Pay particular attention to the sections directly below trees, the corners where joints can loosen, and downpipe outlets where leaves and moss compress into a solid plug.

Moss and Algae on New Tiles

New tiles will start growing moss and algae within a few years, particularly on north-facing slopes that stay damp. Moss holds moisture against the tile surface, and on plain clay or concrete tiles it can slowly work under the edges and into lap joints. On a brand-new roof this is not an immediate problem, but left for a decade or more it starts to degrade performance.

Biocide treatments applied by a roofer - not pressure washing, which can crack tiles and force water under the laps - are the appropriate approach once growth becomes established. Pressure washing a roof is one of the more common mistakes homeowners make when trying to maintain a roof themselves, and it can cause more damage than the moss it removes.

Flat Roof Aftercare

EPDM and torch-on felt flat roofs need less maintenance than old three-layer felt, but they are not maintenance-free. The areas to check on a flat roof are the upstands (where the membrane turns up the wall), the edge trims and any internal outlets or external drains.

• Clear leaves and debris from flat roof surfaces after autumn. Standing debris holds moisture and can eventually abrade the membrane surface.
• Check that edge trims and drip edges are still fully adhered and have not lifted at the corners.
• If there is a parapet wall or upstand, check the cap or coping is still firmly bedded. A loose coping lets water into the wall behind the upstand, which can then track down and under the membrane from behind.
• If you notice any soft or spongy areas underfoot on a flat roof you have access to, do not walk on that section further. Softness usually means the deck below is wet.

Lead Flashings - What to Watch For

Lead flashings at chimneys, parapet walls and abutments are typically the first thing to develop problems on a pitched roof, even a recently fitted one. Lead is a soft metal that expands and contracts with temperature changes, and over time it can pull away from the mortar joint it is tucked into. A small gap is enough to let water track down behind a chimney stack or into a wall cavity.

Checking flashings visually once a year and having any opened joints repointed promptly is far cheaper than dealing with the water damage that follows if they are left. A roofer can repoint a flashing in an hour or two - a plasterer, decorator and possibly a builder are needed to fix what happens if the water gets in.

When to Call a Roofer Rather Than Wait

Some things do not need an immediate call - a little moss on a new roof three years after fitting is completely normal. But some signs should prompt a call sooner rather than later:

• Any damp patches appearing on a ceiling directly below the roof slope
• Water marks appearing on a chimney breast or internal wall adjoining the roof
• A visible tile or slate that has slipped or fallen
• Daylight visible through the loft from a point that was not previously open
• Gutters pulling away from the fascia board under the weight of accumulated debris

The longer water is allowed to sit in a place it should not be, the more it spreads. Timber rots, plasterboard disintegrates and insulation clumps together and loses its effectiveness. Small problems addressed quickly cost a fraction of what the same problem costs once it has been developing for a season.

A Simple Annual Maintenance Checklist

• Clear gutters and check downpipe outlets - ideally autumn and spring
• Visual check of the roof surface from ground level after winter
• Check ridge and hip pointing for cracks or missing sections
• Check lead flashings for any signs of lifting or opened joints
• Clear debris from flat roof surfaces and check edge trims
• Check loft space after heavy rain for any signs of water ingress

None of this requires you to get onto the roof yourself, and none of it is time-consuming. It is the kind of routine that catches things early and keeps a new roof performing as it should.
